Should be easier to review commit by commit. The gist of this commit is: * `onAddRoute` on Android now takes an address+prefix as to minimize parsing * `onAddRoute` recreates the vpn service each time(TODO: is this too bad for performance?) * `on_add_route` and `onAddRoute` returns the new fd * on android after `on_add_route` we recreate `IfaceConfig` and `DeviceIo` and we store the new values * `peer_handler` now runs on a loop, where each time we fail a write with an error code 9(bad descriptor) we try to take the new `DeviceIo` * we keep an [`AbortHandle`](https://docs.rs/tokio/latest/tokio/task/struct.AbortHandle.html) from the `iface_handler` task, since closing the fd doesn't awake the `read` task for `AsyncFd`(I tried it, right now `close` is only called after dropping the fd) so we explicitly abort the task and start a new one with the new `device_io`. * in android `DeviceIo` has an atomic which tells if it's closed or open and we change it to closed after `on_add_route`, we use this as to never double-close the fd, instead we wait until it's dropped. This *might* affect performance on android since we use non-`Ordering::Relaxed` atomic operation each read/write but it won't affect perfromance in other platforms, furthermore I believe the performance gains if we remove this will be minimal.

Connlib
Firezone's connectivity library shared by all clients.

NOTE: This repository is undergoing heavy construction. You could say we're Building In The Open™ in true open source spirit. Do not attempt to use anything released here until this notice is removed. You have been warned.
Building Connlib
Setting the CONNLIB_MOCK environment variable when packaging for Apple or Android will activate the mock feature flag, replacing connlib's normal connection logic with a mock for testing purposes.
- You'll need a Rust toolchain installed if you don't have one already. We recommend following the instructions at https://rustup.rs.
rustup showwill install all needed targets since they are added torust-toolchain.toml.- Follow the relevant instructions for your platform:
- Apple
- Android
- Linux
- Windows
Apple
Connlib should build successfully with recent macOS and Xcode versions assuming you have Rust installed. If not, open a PR with the notes you found.
